J is in their early teens and lives in the countryside. J has been diagnosed with Gender Identity Disorder, goes by the selected pronoun “they”, and takes hormone blockers to suspend puberty. While J’s parents are away, their older sister and her Iranian boyfriend are assigned the duties of house-sitting and looking after J. The three spend time in their parents’ greenhouses, those artificial environments for sheltering organic growth, as well as in the clinic, that technologised institution that shapes their bodies. They recast the family and the medical-industrial complexes through role-play games and test the role of language by reading poetry, telling stories, and playing bilingual games. These adventures become an entry point into the open-ended questions of growth and becoming they are facing.
